Abstract
The utility model discloses the device that the pipeline perforate higher and reliable in quality of a kind of installation effectiveness is shunted.Described drill body comprises body and drill bit, described fixed body comprises retainer plate and lower retainer plate, between body and drill bit, be provided with fairlead, fairlead top coordinates with body spiral, the bar portion of drill bit is positioned at fairlead and coordinates with fairlead rotation, fairlead top is provided with radial hole, and drill bit top is provided with hexagon counterbore, and the upper retainer plate on body lower end and fixed body is spirally connected and is integrated.Rotary guide sleeve during boring, meanwhile, rotary drilling-head top, because fairlead is converted into and is moved downward by rotary manipulation, not only laborsaving, and uniform force application, the quality of boring is also high, when not applying revolving force, fairlead is also difficult for resilience, convenient operation, and operating efficiency is higher.
Description
Technical field
The utility model relates to a kind of device of pipeline flow dividing.
Background technology
Need to lateral be installed on pressure of supply water pipeline under certain conditions time temporarily, generally main pipe system need be closed, then in the position that lateral need to be installed, boring increases threeway, reach lateral object is installed, this mode can be brought inconvenience, and impact life or industrial water, can cause stop work and production when serious.Occurred at present that the boring of not cutting off the water with pressure connects the device of subtube, mainly wellbore part and fixed part, consisted of, fixed part is arranged on the position of wanting perforate on pipeline, and wellbore part is spirally connected and is integrated with fixed part again.Wellbore part is mainly comprised of shell and drill bit, rotary drilling head rod portion in one side during operation, make drill bit rotary-cut pipeline, also need ceaselessly to press down drill bit simultaneously, make drill bit to deferent, apply the pressure of cutting, but it is larger that the mode of this power of applying is affected by human factor, long easy tired consumptive disease of time one, the power applying is also inhomogeneous, is difficult for controlling two actions during operation simultaneously, cause the second-rate of rotary-cut pipeline, when serious, cause road waste.
Summary of the invention
The purpose of this utility model is to provide the device that the pipeline perforate higher and reliable in quality of a kind of installation effectiveness is shunted.
The technical solution of the utility model is: comprise drill body and fixed body, described drill body comprises body and drill bit, described fixed body comprises retainer plate and lower retainer plate, between body and drill bit, be provided with fairlead, described fairlead top caliber is less than bottom caliber, fairlead top coordinates with body spiral, the bar portion of drill bit is positioned at fairlead and coordinates with fairlead rotation, fairlead top is provided with radial hole, drill bit top is provided with hexagon counterbore, and the upper retainer plate on body lower end and fixed body is spirally connected and is integrated.
Dust cap spiral cover is at body top.
The bar portion top of described drill bit is provided with snap ring.
In fixed collar top inner wall, be embedded with seal washer.
In the utility model, adopt the structure that is provided with fairlead between body and drill bit.Fairlead top external diameter is less than lower outer diameter, and fairlead top coordinates with body spiral, and the bar portion of drill bit is positioned at fairlead and coordinates with fairlead rotation, and fairlead top is provided with radial hole, and drill bit top is provided with hexagon counterbore.Therefore, during boring, the front end of the instrument of rotary guide sleeve is inserted to very long rotation in the set radial hole in fairlead top and exert pressure, meanwhile, in the hexagon counterbore with hexagon insertion drill bit top, rotate, and only need to rotate.Because fairlead is converted into and is moved downward by rotary manipulation, not only laborsaving, and also uniform force application, the quality of boring is also high, and when not applying revolving force, fairlead is also difficult for resilience, convenient operation, operating efficiency is higher.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but does not form any restriction of the present utility model.Shown in Fig. 1 and Fig. 2, the utility model comprises drill body and fixed body.Shown in Fig. 3 to Fig. 5, described drill body comprises body 1 and drill bit 3.Shown in Fig. 6 to Fig. 8, described fixed body comprises retainer plate 5 and lower retainer plate 6.Shown in Fig. 4, between body 1 and drill bit 3, be provided with fairlead 2, described fairlead 2 top calibers are less than bottom caliber, fairlead 2 tops coordinate with body 1 spiral, the bar portion of drill bit 3 is positioned at fairlead 2 and coordinates with fairlead 2 rotations, fairlead 2 tops are provided with radial hole, and drill bit 3 tops are provided with hexagon counterbore.Shown in Fig. 1 and Fig. 2, the upper retainer plate 5 on body 1 lower end and fixed body is spirally connected and is integrated.For preventing dust and colliding with, shown in Fig. 1 to Fig. 5, dust cap 4 spiral covers are at body 1 top.For reducing the idle stroke of fairlead 2, need to make the end play of drill bit 3 and fairlead 2 be reduced to minimum, and remain unchanged, shown in Fig. 2 and Fig. 4, in the bar portion of drill bit 3, be provided with snap ring 9, this snap ring 9 is just in time stuck in fairlead 2 tops, and drill bit 3 can not be glided in fairlead 2.For preventing after perforate, the water in pipeline is emerged, and is provided with sealing ring 10, as shown in Figure 2 and Figure 4 between the bar portion of drill bit 3 and fairlead 2.For preventing that the water in pipeline from emerging from fixed body, in upper fixed card ring top inner wall, be embedded with seal washer 7.As shown in Fig. 2, Fig. 7 and Fig. 8.
During installation, the upper retainer plate 5 of fixed body and lower retainer plate 6 are fixed by bolts on pipeline, then body 1 below is screwed on upper retainer plate 5, be fastened as a whole with upper retainer plate 5.Screw off lid, with instrument, insert in the hole of fairlead 2 tops, and rotary guide sleeve 2, there is relative rotary motion with body 1 in fairlead 2, and that body 1 is fixed on retainer plate 5 is motionless, fairlead 2 can only drive drill bit 3 to be forced to together move downward, when drill bit 3 touches pipeline, along with constantly moving downward of fairlead 2, resistance is increasing, when the resistance fairlead 2 that stops the rotation greatly to a certain extent time, use again hexagon rotary drilling-head 3, drill bit 3 is moved in a circle, on pipeline, cut out the circular groove of certain depth, now, the resistance that drill bit 3 is subject to reduces gradually, continue rotary guide sleeve 2, drill bit 3 is moved down.Operation and so forth, until cut regular circular hole on pipeline.The pipeline section scaling off will be by top in the cavity of drill bit 3, because drill bit 3 cavity diameters are greater than drill bit 3 cutting circle diameters, so just can guarantee that cutting tip is stuck in drill bit 3 inner chamber the insides under Water Pressure in pipeline.Finally, rotary guide sleeve 2 round about, drill bit 3 is moved upward, until drill bit 3 rises to flow-guiding mouth 8 tops on body 1, now, the water in pipeline flows in body 1 by the hole getting out, and finally from flow-guiding mouth 8, flows out, only need, from flow-guiding mouth 8 connecting lines, just can reach the object of branch line.After all operations finishes, then dust cap 4 is spun on body 1.
